More than half of the operators of power plants and other "critical infrastructure" say in a new study that their computer networks have been infiltrated by sophisticated adversaries. In many cases, foreign governments are suspected.
The alarming findings come in a survey being released Thursday that offers a rare public look at the damage computer criminals can do to power grids, water and sewage systems and oil and gas companies.
The report, based on interviews with 600 executives and technology managers in 14 countries, was prepared by McAfee Inc., which makes security software, and the Center for Strategic and International Studies in Washington. The respondents aren't named and specifics aren't given about what happened in the attacks.
